This change makes the following arch-specific artifacts to be deployed
to Maven Central (in addition to the main `duckdb_jdbc-x.x.x.x.jar` that
remains unchanged), classifiers:
- `linux_amd64`
- `linux_amd64_musl`
- `linux_arm64`
- `linux_arm64_musl`
- `macos_universal`
- `windows_amd64`
- `windows_arm64`
Each arch-specific artifact contains a native library only for this
particular platform and can be specified in Maven dependencies with the
following syntax:
```xml
<dependency>
<groupId>org.duckdb</groupId>
<artifactId>duckdb_jdbc</artifactId>
<version>1.x.x.x</version>
<classifier>linux_amd64_musl</classifier>
</dependency>
```
Note that Windows and Linux-musl AArch64 artifacts are renamed from
`aarch64` to `arm64` to align with wider DuckDB arch naming.
Additionally an artifact without any native library is deployed with a
`nolib` classifier. It is intended to be used with an externally
provided native library, see duckdb#421 for details.

This PR is a continuation of duckdb#447 PR to allow using `duckdb_jdbc-x.x.x.x-nolib.jar` along with a JNI native library, that is loaded directly from file system. It extends the idea from duckdb#421 (and supersedes it) implementing the following logic: 1. if the driver JAR has a bundled native library (for current JVM os/arch), then this library will be unpacked to the temporary directory and loaded from there. If the library cannot be unpacked or loaded - there is no fallback to other methods (it is expected that `-nolib` JAR is used for other loading methods) 2. if the driver JAR does not hava a native library bundled inside it, then it will check whether a JNI native libary with the DuckDB internal naming (like `libduckdb_java.so_linux_amd64`) exists in file system next to the driver JAR (in the same directory). If library file is found there - then the driver will attempt to load it. If the file is found in file system, then it is expected that is can be loaded and there is no fallback to loading by name. 3. if the native lib is not found in the same directory, then, like in duckdb#421, the driver tries to load it using `duckdb_java` name (that will be translated by JVM to a platform-specific name like `libduckdb_java.so`). Testing: new test added that covers loading from the same dir and loading by name. Fixes: duckdb#444
